@ruiting @linas please check newly added test sentences. 
yes @linas  this is a caputure of current RelEx output. It's POS tagged with ".a-c" which is correct. Also "is bigger" is connected by a "Pam" link which also correct I guess.
In other cases like "New York is much bigger than Boston." current RelEx dosent normalize "bigger" to "big" . same happens here also - "France is a bigger country than Britain."
